The Federal High Court in Abuja will rule on the bail application of the leader of the Indigenous People of Biafra (IPOB), Nnamdi Kanu, on April 25.
Kanu and three others are on trial for โtreasonโ.
Justice Binta Murtala Nyako will on April 6 hear the application seeking variation on the earlier ruling on protection of witnesses in the matter through the use of screen or mask.
Justice Nyako told the defendants that despite their applications, she would not change her mind on the protection of witnesses, as long as they remain with security operatives.
According to her, their participation in the case is part of their duties, as such she would not expose them because of future engagement.
The defendants, however, insisted that they would still bring their application on the grounds that her quashing of six of the earlier 11 charges, has made the case a fresh one.
They said they were inclined to seek for a variation on the witness protection order.
Kanu, a director of Radio Biafra, is remanded in Kuje prisons by the Department of State Services (DSS).
He, David Nwawuisi, Benjamin Madubugwu and Chidiebere Onwudiwe were charged with treasonable felony by the Federal Government for leading IPOB movement to ask for an independent Biafra out of Nigeria.
The Federal High Court sitting in Abuja recently struck out six of the 11-count charges filed against the defendants for being incompetent.
